stephane campinas created ARROW-7206: ----------------------------------------
Summary: avoid string concatenation when calling Preconditions#checkArgument Key: ARROW-7206 URL: https://issues.apache.org/jira/browse/ARROW-7206 Project: Apache Arrow Issue Type: Improvement Components: Java Reporter: stephane campinas Assignee: stephane campinas Attachments: after.png, before.png Preconditions#checkArgument is called in VectorLoader with the String message already built. This causes some noticeable overhead as can be seen from the attached flame graphs. Calling checkArgument with an error template instead avoids the call to StringBuilder as can be seen in the `after` image. -- This message was sent by Atlassian Jira (v8.3.4#803005)
